Remon is much like Kizuna in personality, though not as clumsy, she is also one of the members of the Transformation and Secret Clubs. She tends to be more serious than Kizuna, though she doesn't miss the chance to get excited about matters such as love and attraction.
Remon and Kizuna seem to have known each other long enough to become best friends and in effect they are almost always seen together. As stated above, she may be in an intimate relationship with Kizuna, though this is still uncertain. However, she appeared decidedly unhappy when Kagome was sharing a room with them during summer school.
